hi,

I'm trancoding a live event with vlc 0.8.6e (in a VLM conf file).
I changed server because of cpu usage (too high), now I have bi xeon 2.6 
GHz.

It seems to me that VLC doesn't use several cpu, I even tested threads=0 
1 2 3 or 4... and same result.

I get that with top :

top - 11:40:46 up 1 day, 23:11,  2 users,  load average: 1.04, 0.98, 0.84
Tasks:  70 total,   1 running,  69 sleeping,   0 stopped,   0 zombie

  4321 nvanhaut  20   0  156m  38m 7572 S  101  1.0   6:51.42 vlc

any idea how to use multithreads ?

Thanks

regards

Nicolas
